ATTACHMENT Eon ILows.

To all who'mz'ktlma' concern.' l Be it knownt l'at I, JACOB H. RrzoR, acitizen of the United States, andA a resident of Van Wert, in the=countyAofV`a`nl7V ift andv l' State of Ohio, have invented a certainne-wffprovision of an improved attachment of this class which is simple andinexpensive in its construction, efficient in its operation and capableof being easily and quickly `attached to a plow.

Further objects and advantages of the invention will be apparent fromthe following detailed description thereof.

While the invention, in its broader aspect, is capable of embodiment innumerous forms, a preferred embodiment thereof is illustrated in theaccompanying drawings, in which,-

Figure l is a rear perspective view of a plow embodying the invention.Fig. 2 is a fragmentary front perspective view thereof, and Fig. 3 is ahorizontal sectionV of the at'- tachment. l

Referring to the drawings, 1 designates a plow bottom of the customaryor any suitable form, and 2 the beam carrying the same.

The attachment embodying the invention comprises a .fin cutter 3, which,in the present instance, is of L-form with its lower arm extendingrearward along the land side of the plow l and secured thereto by bolts4 or in any other suitable manner. The upright portion of the fin 3forms the cutting blade and extends at its upper end preferably to aheight which is equal to, or greater than the height of the plow bottom.A frog 5v Specification, of Letters Patent.

ofj the frog u-.andhas its nose or forward edge if portion preferably lentering.` a. curve or recess in thel adjacent side of the fin4 3 ashortidistance -at= the rear-A of Iits cutting edge 'so as-to preventthe accumulation of weeds or. other matter between the fin cutter andjointer. The jointer blade 7 is similar in form to the mold board of aplow and is preferably adjustably connected to the frog l. Suchadjustment in the present instance, is accomplished by the provision inthe frog 5 of slots 9 through which the bolts 8 project.

A bracket arm 10, in the present instance of L-form, is adjustablyclamped at one end to the plow beam 2 by the clamp 11 and extendsforward therefrom with its free arm projecting downward between theflanges of the frog 5 and secured to the cutter fin engaging flangethereof by the bolt 6. A divider rod` l2 extends upward and forward fromthe inner side of the jointer blade 7 and serves to gather trash, weedsand other matter and prevent the accumulation thereof around the baseportion of the plow beam 2. The provision of this rod is found to bequite an important feature in the use of my attachment.

I wish it understood that my invention is not limited to any specificconstruction, arrangement or form of the parts, as it is capable ofnumerous 'modifications and changes without departing from the spirit ofthe claims.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is L- l. The combination with a plow bottomand the beam therefor, of a bracket arm projecting forward and downwardfrom the lower rear portion of said beam, a frog'carried by saidbracket, a cutter fin secured to said frog and extending downward andrearward therefrom at the land side of the plow bottom, andV a jointerblade carried by said frog over the mold board side of the plow bottom.

Y, 2. The combination with a plow bottom and the carrying beam therefor,of ai bracket arm adjustably extending forward from a lower rear portionof said beam, a frog carried by said bracket in advance of the plowbottom, L a cutter fin extending downward from said frog in advance ofthe plow bottom and secured at its lower portion to the outer side ofthe land side of the plow botby said frog and extending from theladje,"-

cent side of the fm cutter over vthe forward 5 bottom.
